This Standard includes recommended practices concerned
primarily with the prevention of water damage
to steam turbines used for fossil-fuel-fired electric power
generation. The practices address damage due to water,
wet steam, and steam backflow into a steam turbine.
The practices are applicable to conventional steam cycle,
combined cycle, and cogeneration plants. The practices
cover design, operation, inspection, testing, and maintenance
of those aspects of the following power plant
systems and equipment concerned with preventing the
induction of water into steam turbines:
- (a) motive steam systems
- (b) steam attemperation systems
- (c) turbine extraction/admission systems
- (d) feedwater heaters
- (e) turbine drain system
- (f) turbine steam seal system
- (g) start-up systems
- (h) condenser steam and water dumps
- (i) steam generator sources
Any connection to the turbine is a potential source of
water either by induction from external equipment or by
accumulation of condensed steam. The sources treated
herein specifically are those found to be most frequently
involved in causing damage to turbines. Althoughwater
induction into the high and intermediate pressure turbines
has historically been recognized as the most damaging,
experience has shown that water induction in
low pressure turbines can cause significant damage and
should also be taken seriously.
This Standard is not intended to impose new requirements
retroactively for existing facilities.
